ActionScript 3.0 :: Antialias Bitmap When Rotating?

it is more or less like this: i have some things drawn into a container sprite; those things may include text and other stuff. then i create a bitmapdata and i render all that stuff into the bitmapdata, so when rendering it does not slow down too much, and i put that bitmapdata into a bitmap, and that bitmap into another sprite (this is because i pass it as parameter to a function set to receive a sprite, not a visual object). when i rotate the sprite that contains the bitmap, the picture looks kinda blocky, and the text appears very ugly, specially when there is rotation, even if there is no angle yet (probably due to rounding it may take as different than zero), the text appears with some lines that crosses it,probably due to rounding problems. i saw there was an option to smooth the bitmap when scaling though i have not read too much into it yet, i have also thought about adding a blur filter if rotation != 0, but i believe it would be making a mess out of it. It is working fine now, but it looks ugly when rotating, how do i set up a sprite so it antialiases when rotating?
